BACKGROUND OF THE INVENTION

1. Technical Field of the Invention

This invention relates generally to wireless communication systems andmore particularly to integrated circuits of transceivers operatingwithin such systems.

2. Description of Related Art

Communication systems are known to support wireless and wire linedcommunications between wireless and/or wire lined communication devices.Such communication systems range from national and/or internationalcellular telephone systems to the Internet to point-to-point in-homewireless networks. Each type of communication system is constructed, andhence operates, in accordance with one or more communication standards.For instance, wireless communication systems may operate in accordancewith one or more standards including, but not limited to, IEEE 802.11,Bluetooth, advanced mobile phone services (AMPS), digital AMPS, globalsystem for mobile communications (GSM), code division multiple access(CDMA), local multi-point distribution systems (LMDS),multi-channel-multi-point distribution systems (MMDS), radio frequencyidentification (RFID), Enhanced Data rates for GSM Evolution (EDGE),General Packet Radio Service (GPRS), and/or variations thereof.

Depending on the type of wireless communication system, a wirelesscommunication device, such as a cellular telephone, two-way radio,personal digital assistant (PDA), personal computer (PC), laptopcomputer, home entertainment equipment, RFID reader, RFID tag, et ceteracommunicates directly or indirectly with other wireless communicationdevices. For direct communications (also known as point-to-pointcommunications), the participating wireless communication devices tunetheir receivers and transmitters to the same channel or channels (e.g.,one of the plurality of radio frequency (RF) carriers of the wirelesscommunication system or a particular RF frequency for some systems) andcommunicate over that channel(s). For indirect wireless communications,each wireless communication device communicates directly with anassociated base station (e.g., for cellular services) and/or anassociated access point (e.g., for an in-home or in-building wirelessnetwork) via an assigned channel. To complete a communication connectionbetween the wireless communication devices, the associated base stationsand/or associated access points communicate with each other directly,via a system controller, via the public switch telephone network, viathe Internet, and/or via some other wide area network.

For each wireless communication device to participate in wirelesscommunications, it includes a built-in radio transceiver (i.e., receiverand transmitter) or is coupled to an associated radio transceiver (e.g.,a station for in-home and/or in-building wireless communicationnetworks, RF modem, etc.). As is known, the receiver is coupled to anantenna and includes a low noise amplifier, one or more intermediatefrequency stages, a filtering stage, and a data recovery stage. The lownoise amplifier receives inbound RF signals via the antenna andamplifies then. The one or more intermediate frequency stages mix theamplified RF signals with one or more local oscillations to convert theamplified RF signal into baseband signals or intermediate frequency (IF)signals. The filtering stage filters the baseband signals or the IFsignals to attenuate unwanted out of band signals to produce filteredsignals. The data recovery stage recovers raw data from the filteredsignals in accordance with the particular wireless communicationstandard.

As is also known, the transmitter includes a data modulation stage, oneor more intermediate frequency stages, and a power amplifier. The datamodulation stage converts raw data into baseband signals in accordancewith a particular wireless communication standard. The one or moreintermediate frequency stages mix the baseband signals with one or morelocal oscillations to produce RF signals. The power amplifier amplifiesthe RF signals prior to transmission via an antenna.

While transmitters generally include a data modulation stage, one ormore IF stages, and a power amplifier, the particular implementation ofthese elements is dependent upon the data modulation scheme of thestandard being supported by the transceiver. For example, if thebaseband modulation scheme is Gaussian Minimum Shift Keying (GMSK), thedata modulation stage functions to convert digital words into quadraturemodulation symbols, which have a constant amplitude and varying phases.The IF stage includes a phase locked loop (PLL) that generates anoscillation at a desired RF frequency, which is modulated based on thevarying phases produced by the data modulation stage. The phasemodulated RF signal is then amplified by the power amplifier inaccordance with a transmit power level setting to produce a phasemodulated RF signal.

As another example, if the data modulation scheme is 8-PSK (phase shiftkeying), the data modulation stage functions to convert digital wordsinto symbols having varying amplitudes and varying phases. The IF stageincludes a phase locked loop (PLL) that generates an oscillation at adesired RF frequency, which is modulated based on the varying phasesproduced by the data modulation stage. The phase modulated RF signal isthen amplified by the power amplifier in accordance with the varyingamplitudes to produce a phase and amplitude modulated RF signal.

As yet another example, if the data modulation scheme is x-QAM (16, 64,128, 256 quadrature amplitude modulation), the data modulation stagefunctions to convert digital words into Cartesian coordinate symbols(e.g., having an in-phase signal component and a quadrature signalcomponent). The IF stage includes mixers that mix the in-phase signalcomponent with an in-phase local oscillation and mix the quadraturesignal component with a quadrature local oscillation to produce twomixed signals. The mixed signals are summed together and filtered toproduce an RF signal that is subsequently amplified by a poweramplifier.

As is generally known, transceivers, such as the ones described above,are in the physical (PHY) layer of the communication stack. The otherlayers include medium access control (MAC) layer, network layer,transport layer, session layer, presentation layer, and applicationlayer. For a host communication device to support a wirelesscommunication, it includes firmware to process each of these layers andalso includes firmware to process an operating system and userapplications (e.g., digital camera, email, web browsing, voicerecorder). Such a communication device includes multiple integratedcircuits to support these various functions. For instance, an IC may beused to provide the RF portion of the PHY layer, another IC may be adigital signal processor (DSP) to support the baseband PHY layer andaudio codec functions, yet another IC for supporting the lower layers ofthe communication stack (e.g., MAC, network and transport), while adifferent IC supports the upper layers of the communication stack, theoperating system, and the user applications. Typically, the ICsupporting the upper layers of the communication stack, the operatingsystem, and the user applications is a high speed, high powermicroprocessor to provide a desired level of performance.

In recent technological advancements, a multiple function processingcore of a DSP for the baseband PHY layer and audio codec functions, afirst microprocessor for the lower layers, and a second microprocessorthe upper layers, the operating system, and the user applications hasbeen implemented in a single IC package. While this implementationprovides greater integration, it has relatively high power consumption.

Despite the recent technological advancements discussed above, there isa continued desire for wireless communication devices to supportmultiple standards, for further integration, and for decreased powerconsumption. However, such desires have gone unrealized when it comes toimplementing baseband and RF on the same chip for multiple wirelesscommunication standards with the upper layers of the communicationstack, the operating system and the user applications in a powerefficient IC.

Therefore, a need exists for an integrated circuit (IC) that implementsbaseband and RF of multiple wireless communication standards on the sameIC die with the upper layers of the communication stack, the operatingsystem and the user applications in a power efficient IC.

Furthernote that the wireless communication devices 18-32 may be laptop hostcomputers 18 and 26, personal digital assistant hosts 20 and 30,personal computer hosts 24 and 32 and/or cellular telephone hosts 22 and28. The details of the wireless communication devices will be describedin greater detail with reference to one or more of FIGS. 2-23.

Wireless communication devices 22, 23, and 24 are located within anindependent basic service set (IBSS) area and communicate directly(i.e., point to point). In this configuration, these devices 22, 23, and24 may only communicate with each other. To communicate with otherwireless communication devices within the system 10 or to communicateoutside of the system 10, the devices 22, 23, and/or 24 need toaffiliate with one of the base stations or access points 12 or 16.

The base stations or access points 12, 16 are located within basicservice set (BSS) areas 11 and 13, respectively, and are operablycoupled to the network hardware 34 via local area network connections36, 38. Such a connection provides the base station or access point 1216 with connectivity to other devices within the system 10 and providesconnectivity to other networks via the WAN connection 42. To communicatewith the wireless communication devices within its BSS 11 or 13, each ofthe base stations or access points 12-16 has an associated antenna orantenna array. For instance, base station or access point 12 wirelesslycommunicates with wireless communication devices 18 and 20 while basestation or access point 16 wirelessly communicates with wirelesscommunication devices 26-32. Typically, the wireless communicationdevices register with a particular base station or access point 12, 16to receive services from the communication system 10.

The data RF section 314 converts the outbound data symbol stream 324into an outbound RF data signal 326 having a carrier frequency in thefirst frequency band (e.g., 890-915 MHz) in accordance with the one ormore existing wireless communication standards, new wirelesscommunication standards, modifications thereof, and/or extensionsthereof (e.g., EDGE, GPRS, etc.). In one embodiment, the data RF section314 receives the outbound data symbol stream 324 as Cartesiancoordinates. In this embodiment, the data RF section 314 mixes thein-phase components of the outbound data symbol stream 324 with anin-phase local oscillation to produce a first mixed signal and mixes thequadrature components of the outbound data symbol stream 324 with aquadrature local oscillation to produce a second mixed signal. The dataRF section 314 combines the first and second mixed signals to produce anup-converted data signal. The data RF section 236 then amplifies theup-converted data signal to produce the outbound RF data signal 326.Note that further power amplification may occur after the output of thedata RF section 314.

In other embodiments, the data RF section 314 receives the outbound datasymbol stream 324 as Polar or hybrid coordinates. In these embodiments,the data RF section 314 modulates a local oscillator based on phaseinformation of the outbound data symbol stream 324 to produce a phasemodulated RF signal. The data RF section 314 then amplifies the phasemodulated RF signal in accordance with amplitude information of theoutbound data symbol stream 324 to produce the outbound RF data signal326. Alternatively, the data RF section 314 may amplify the phasemodulated RF signal in accordance with a power level setting to producethe outbound RF data signal 326.

For incoming data communications, the data RF section 314 converts theinbound RF data signal 328, which has a carrier frequency in the firstfrequency band (e.g., 890-915 MHz) into an inbound data symbol stream330. In one embodiment, the data RF section 314 extracts Cartesiancoordinates from the inbound RF data signal 328 to produce the inbounddata symbol stream 330. In another embodiment, the data RF section 314extracts Polar coordinates from the inbound RF data signal 328 toproduce the inbound data symbol stream 330. In yet another embodiment,the data RF section 314 extracts hybrid coordinates from the inbound RFdata signal 328 to produce the inbound data symbol stream 330. Theinterface module 312 provides the inbound data symbol stream 330 to thedata baseband processing module 318 when the IC 150 is in the data mode.

The data baseband processing module 318 converts the inbound data symbolstream 330 into inbound data 332.
